, specification.

This invention relates to improvements in open fire place structures, and particularly to a fire place device that may be set or placed in the ordinary fire place, as commonly constructed in building the ordinary dwellin or house.

It is an object of the invention to provide means whereby the usual fire place may be utilized, with its cheerful fire, without the escape of most of the heat developed, as usually occurs with the average fire place where a large percentage of the heat goes up the chimney flue with the products of combustion.

It is also an object of the invention to provide a portable fire place heater, having an outer casing adapted to fit within a fire place, and arranged to take the cold air from the floor of the room and return it in heated condition to the room again, an inner heating fire place being spaced within the said casing and having pipe connection with the fireplace flue for delivering the products of combustion therein.

It is a further object of the invention to provide a heating structure of this type with a fire lighting mechanism, capable of igniting the various kinds of fuel, that may be used in the fire box or inner heating chamber of the device.

With these and other objects in view, the invention comprises certain novel constructions, combinations and arrangements of parts as will be hereinafter more fully described and claimed.

In the accompanying drawing, forming a part of this specification:

Figure 1, is a front elevation of the fire place structure of the present invention, located in an ordinary fire place.

Fig. 2, is a vertical central sectional view taken through said fire place and structure, from front to rear.

Fig. 3, is ahorizontal sectional view through the fire place just above the fire place structure or heating device, the said device being shown in top plan.

Fig. 4, is a horizontal sectional view taken through the device on the line 4-4 of Fig. 2.

Fig. 5, is a fragmentary sectional view through one end of the grate and the lighting mechanism, showing the same upon an enlarged scale.

The device of the present invention is designed to provide a fire place structure that may be set or loosely placed within the ordinary fire place, whereby there is afforded a fire place within a fire place, with a heating space extending entirely between the same, so that cool air taken in at the bottom or at the floor may be passed through the said space, thoroughly heated and re turned to the room again from which it was ,7

taken.

The details and features of the invention will now be more specifically described reference being had to the accompanying drawing in which, 5 indicates a fire place as usually constructed in a chimney piece or other place, 6 the flue of the fire place. The device of this invention is formed with an outer casing 8, intended to rest directly upon the hearth, so as to receive the cool or cold air directly from the floor or lowest part of a room. The said casing 8 fits within the walls of the fire place 5, at the sides and back, and at the top is usually peaked or arched to form something of a dome, and thus facilitate the delivery of the heated air at the front through an outlet flue 9. The front wall of the casing 8 is formed with an opening coinciding with the opening in the front wall of the fire box or inner fire place 10.

The inner fire place or box 10, is supported on legs or standards 11, which rest on the bottom of the casing; 5, so that a large hot air space is permitted within said casing 5 on all sides of the fire box 10 except at the front, as will be readily understood by reference to Figs. 2 and 4 of the drawing. The front wall of said fire box 10 is provided with a large opening 12, coinciding with the opening in the front wall of the casing 5, permitting the fire to be seen, and enjoyed as in the case of any usual fire place.

A smoke pipe 13 passes from the top of the fire box 10, through the top or dome of the casing 5, into the chimney flue 6, any desired number of sections of piping being employed for the purpose, as shown in Fig. 2. 7

Near the lower wall or fioor of the fire box 10, is mounted a grate support or frame 14, upon which is supported a grate of ordinary construction. The grate may be formed with trunnions 16 adapted to engage recesses or bearings 17, formed in the support 14, whereby the grate may be tipped for dumping ashes when desired. A proaje'ction 18 at the back of theframe or support.14, prevents the grate from dropping when in horizontal position. The sides of v :the said support 14 preferably incline in- .Wardly and downwardly toward the grate,

SQ s to tend to centralize the fire or burning fuel upon the grate, as will be readlly understoodby reference to the drawing.

The fire box 10 is preferably provided with a fuel lighting means, generally a gas burner 19, which may be made in the form of a pipe, extending around the grate beneath the lower inner edge of the support 14, and having jets or holes 20 therein and in the under side. of the pipe to prevent ashes and-dirt from getting into them and clogging them; The said holes 20 are arranged to direct the gas flames inwardly beneath the grate, so that they will rise through the said grate and ignite the fuel in the fire box 14. The burner 19 is gen erally supported by hangers 21, depending from the support or. frame 14. The said burner 19 is connected with a gas supply pipe 22, which is usually present in the modern fire place, and a stop cook or valve 23, controls the flow of gas to the burner, a long handle being provided for the said valve as at24, by which it may be operated from the front of the fire place.

A sufficient space is left in the fire box 10,-below the grateto receive an ash pan 25.

.8, and asbestos or other non-heat conducting material is preferably placed between the said plate 28 and the casing 8 to prevent the. front plate from becoming hot to the touch. The door 26 is generally'hinged to the said front plate, as shown in the drawing. Below the door 26 andextending to the floorjis a large air receiving opening in 'gthe-said front; plate 28, and an ornamental grating is preferably placed over the same as at 29.

Near the top the said front plate 28 is provided with another opening coinciding with the discharge outlet of the heat outlet fine 9 and an ornamental grating may also be provided for this opening as indicated at 30.

In use the fire place device described ma y be set into a fire place which it will approximately fit, and the front be adjusted in place, to give about the appearance indicated in Fig. 1.

The fuel, of any desired sort is placed in the fire box 10, and where gas can be had, the burner 19 is lighted. The flames from the burner turning inwardly and upwardly, will quickly ignite the fuel, after which the gas may be turned off. The damper 27 is regulated to control the draft beneath the grate. All smoke and products of combustion will be carried by the pipe 13 into the chimney fine. A large quantity of air will pass through the grating 29, to be heated by contact with the thin walls of the fire box 10, within the casing 5, and rising will pass out through the outlet flue 9 into the room again.

It will be evident that the details of the device may be considerably altered. and its present invention.

lVhat is claimed is:

1. Afire place heater comprising a combustion. chamber having an open front, a burner mounted in the said combustion chamber for heating the same, an inclosing casing entirely surrounding the said combustion chamber and having a front opening coinciding with the front opening in the said combustion chamber, an air space being left between the casing at the sides, back, bottom and top, the said casing having lower and upper openings beneath and above said combustion chamber for the inlet and outlet of air within the room, and a fire place front plate having an opening coinciding with that of the combustion chamber and casing and having lower and upper openings coinciding with the lower and upper openings in the said outer casing.

and means for delivering the products of combustion into the chimney fine of the fire place.

2. A fire place heating device having an inclosed casing set in the fire place, a combustion chamber having inclosed walls set in said casing, a front fire place plate covering said fire place, casing and combustion chamber, said casing, combustion chamber and plate having a large fire opening registering with each other, means for admitting draft .into said combustion chamber Ill) bustion into the chimney flue from the combustion chamber of said heating device.
